I should have done this first recently, and didn’t I wasted time and money on a 2005 Mustang V6 (manual trans) no start/turn-over condition. If it starts: than you know the battery, terminals, cables, trigger wire, ground, starter, key (if it has a chip) and ignition switch are OK. When you identify the (usually two) pins that switch the circuit (not the control side of the relay) use a paperclip and momentarily jump them at the fuse/relay box under the hood to start the car ( make sure your key is inserted and turned to the ‘on’ position before doing a relay bypass). Pull the relay and look for the diagram on the side of the relay. Look in the engine compartment relay box and find the starter relay. If you have a manual trans make sure the car is in neutral, and e-brake is engaged.If you have an auto trans make sure the car is in park.For what it’s worth, you can easily determine which side of the starting circuit is the issue.
